Did some shooting yesterday
Yesterday I spent the majority of the day cleaning my 7 RM barrel and loading up some new loads and going and testing them out. I also got my rifle back from my smith complete with a Holland muzzle brake. I am going elk hunting Nov 4th, so I'm kinda in a hurry to get a new load figured out and the drop chart. Anyways, I am using 175g SGK's under RL-22. I loaded up 3 loads the night before using 61, 62, 63g. 61g shot the best by far. As I went up in charge weight, groups opened up. So I figured I would work around 61 as that gave me a 1" group at 100 yards. Soo, back to the bench. I loaded up 3 more laods, this time 60.4g, 60.7g, and again 61g. The 60.4g shot the best with 4 shots going into .4", and the 5th opened it up. I dont normally do 5 shot groups, I just had 5 of that load, loaded up for 2 barrel foulers. Anyways, the 60.7 and 61g load sucked. From 60.4g, to 60.7g was a big difference. So I think I might try the low end of 60g and hope to be in the middle of the sweet spot, that way if I"m either high or low a tad, I'll still be in there. Velocity is a slow 2800fps, but I was kinda expecting that. I also had about 5 other loads to shoot that I already knew were contenders. I tried 162g amax with 61g RL-22 and it shot a nice .4" cluster at 2875fps. Once again, quite slow, but expected with Rl-22. Seems to shoot accurately at the lower end of the scale [img]/ubbthreads/images/graemlins/frown.gif[/img] So that led me to try 162g amax w/Retumbo. I went 71.5g and 73g. 71.5g shot a .9" group and was going 3075fps. 73g shot a .8" group and was going 3175fps. That load seems a little hot maybe??? Its 300fps faster then the Rl-22 load. I also tried one of my 140g btip loads consisting of 68.5g RL-22. It shot .6", first 2 touching, and at 3250fps. Also tried my 168g Berger VLD load and it shot .9", first two touching at 3000fps. I can say I'm pretty happy with the brakes performance. It dont kick at all, especially since I"m firing off a lead sled as well. I can pretty much see my own impacts at 14x if the range is over 400 yards or so. Not to bad, definately got rid of the muzzle flip, which I hate. I have the target with all the groups shot on it from yesterday, but the camera's out at my parents house. I'm going to go load up some more and test out 400 yards today, so more testing to come.
